Fiala was acquired in a deadline deal with the Nashville Predators in exchange for Mikael Granlund. The trade was made by ex-Wild general manager Paul Fenton, who had previously been the assistant GM in Nashville.

In 83 games split between the two clubs, Fiala registered 12 goals and 39 points in 2018-19. This marked a bit of a down year compared to his 23-goal, 48-point output in 2017-18.

The 23-year-old will compete for top-six minutes in his first full campaign with the Wild.
